无论我们对理解文学作品的方式进行何种分析,都必须首先对两个分析赖以建立的前提予以限定。其一,任何分析都必须搞清对“谁”的理解文学的方式进行分析。任何一个理论家都须以某种方法确定这个“谁”究竟是哪些人,其次,理论家必须弄清楚他所确定的这些人以什么标准衡量某一部作品是否是文学作品。理论家如果开初便意识到了这两个前提的存在,问题也就迎刃而解了,但如果他开始时未曾留意,待到讨论深入后,便会造成混乱。对于第一个问题的合理回答是。

TLC Determination of Marmesin, a Biologically Active Marker from Feronia Limonia L.

引用

American Journal of Plant sciences 2010年第1期1卷 12-16页

作者： Mahendra Jain Ashish Trivedi s.h. Mishra 不详

Feronia limonia Linn. (Rutaceae) have gained traditional therapeutic importance owing to their high essential oil and coumarins content. Marmesin, a furanocoumarin was identified by TLC and isolated by column chromatography and further purified by Preparative TLC. Presently, there is no appropriate TLC based method available for standardization of F. limonia. A simple, sensitive and accurate high performance thin layer chromatographic (hPTLC) method has been developed for the estimation of marmesin in the methanolic extract of stem bark of Feronia limonia. hPTLC was performed on precoated silica gel 60F254 aluminium plates (20 cm × 20 cm) with Chloroform: Methanol (9.5:0.5), as mobile phase. Quantitative evaluation of the plate was performed in the absorption-reflection mode at 338 nm. The calibration curve was linear in the concentration range of 20 – 100 ng spot–1. The method was validated for precision, repeatability and accuracy. The technique has been applied, for the first time, for the estimation of marmesin. The proposed method was found to be robust, precise, and accurate, it therefore holds potential for detection, monitoring and quantification of marmesin in Feronia limonia and its related formulation.

Comparative chemical sensor for detection of chromium(Ⅵ) in aqueous solution

Optoelectronics Letters 2025年第1期21卷 21-27页

作者： sura h.AL-REKABI A.A.ALWAhIB Electrical Technique Department Al Suwayrah Technical Institute Middle Technical University Laser and Optoelectronics Department University of Technology-Iraq

A process for purifying aqueous solutions containing heavy and toxic metals such as chromium（Cr） has been investigated. One of the extremely harmful pollutants in rivers and seawater is the heavy metal ions due to their direct impacts on human, animals and plants are hexavalent Cr（Ⅵ）. Consequently, highly sensitive sensor to detect Cr is essential. surface plasmon resonance（sPR） technique has attracted huge research interest in detecting heavy metals specifically. In this study, three types of prism-based sPR sensor, gold（Au）/silver（Ag）, Au/polyaniline（PANI） and Au/titanium dioxide（TiO2） nanostructured films, are investigated as potential sensing material to detect the presence of Cr（Ⅵ） ions in water. The base Au layer with thickness of 48.3 nm is deposited on a glass slide for all sensors. For Au/Ag, Au/PANI nanofibers and Au/TiO2sensor films, the Cr（Ⅵ） concentration is varied from 1 ppm to 15 ppm with sensitivity of 0.270 °ppm-1, 0.082 °ppm-1and 0.039 °ppm-1, respectively. Based on these results, the Au/PANI nanofibers are the most sensitive to Cr（Ⅵ） among the tested sensing materials.

Neurological disorders including neurodegenerative diseases,brain tumors,and stroke are the second leading cause of death and the greatest cause of disability ***,it remains challenging to achieve effective drug delivery to the central nervous system for treatments of neurological diseases due to the blood-brain barrier(BBB).The function of the BBB is regulated by the physiological interactions between various types of cells in the neurovascular unit(NVU).In the NVU,the brain vasculature of the BBB is surrounded by brain pericytes,brain astrocytes,neurons,and microglia(Figure 1).Moreover,the NVU at the levels of arteries and veins includes contractile smooth muscle cells(s.h.effer and Iadecola,2021).
